Stenting versus surgery in obstructed malignant colorectal cancer—a review of short and long-term results

Obstructed colorectal cancers (CRCs) continue to be challenging to manage. Apart from surgical resection, the use of self-expanding metallic stents (SEMS) has become increasingly popular. SEMS could potentially allow for the conversion of an emergency operation into a semi-elective procedure, allow for the optimization of the patient's physiology, avoid the requirement for a stoma, as well as allow for a minimally-invasive approach to be adopted. This review article therefore highlights the evidence available in the literature pertaining to the use of SEMS in obstructed CRCs.
